2 Claims.

The present invention relates to the mounting of panels of building material in a wall and it has particular relation to the mounting oi panels or slabs of so-called Foamglas" to provide yan insulative structure.

One object of the invention is to provide simple and convenient means for mechanically securing the panels or slabs to provide a continuous insulative wall.

A second object is to provide an insulative wall of a cellular glass in which the slabs or panels are positively mechanically secured to a. framework without exposure of fastening elements upon the interior side.

A third object is to provide a structure of the foregoing type in which the assembly of the panels in the wall is eiected with a minimum of effort.

These and other objects of the invention will be apparent from consideration of the following specification and the drawings upon which it is based.

Heretofore a highly durable and eflicient insulating material has been prepared by heating a mixture of nely pulverized glass and a gasproducing agent, such as calcium carbonate or carbon black in pan-like molds of suitable diing a highly cellulated slab of glass, which whenl suitably cooled and annealed possessed high insulative value against the transmission of heat. These foamlike bodies also possessed the high resistance to chemical agencies and permeation by moisture characteristic of glass.

Heretofore it has been customary to mount these panels to provide an insulative layer by cementing or bonding them to a continuous protective and supporting backing structure, such as a wall or the like. It has heretofore been difcult if not impossible merely mechanically to secure the panels or slabs in place in or upon a framework which did not provide a continuous backing to which they could be cemented.

The present invention contemplates the provision of a simple system for securing the panels `as a continuous wall in a suitable framework.

More specifically the invention contemplates securing the panels in place by means of mounting bars having appropriate flanges for engaging edge grooves of the individual panels or slabs one edge in such manner that each slab is individually supported without impressing strain upon contiguous units and further having piercing means (Cl. 'l2- 19) 2 for engaging contiguous edges of the neighboring panels.

For a better understanding of the invention reference may now be had to the accompanying drawings in which like numerals refer to like parts throughout.

In the drawings Fig. 1 is a sectional view of a room or duct constructed in accordance with the provisions of the invention;

Figs. 2, 3, 4 and 5 are fragmentary sectional views illustrating upon a larger scale various details of the construction shown in Fig. 1; 1

Fig. 6 is an isometric view of one of the flange bars or rails employed to support the slabs or panels;

Fig. 'lis an isometric detail of a clip for secur ing the ungrooved edge of the nal row of slabs or panels; y Y

Figs. 8 and 9 are fragmentary sectional views of modifications of the construction for securing the ungrooved edges of the lfinal course of slabs;

Figs. 10 and 11 are isometric views of details of the modifications shown in Figs. 8 and 9;

Figs. 12 and 13 are isometric views of modified forms of securing rails;

Fig. 14 is a sectional view of the form shown in Fig. 12; and I Fig. 15 is an isometric View of one of the cellular glass slabs.

In the construction as shown in Fig. 1 a framework I9, such as a frame for an insulative duct, includes vertical members 20 and 2| secured together at their upper extremities by a transverse member 22 and resting at their lower extremities upon a suitable floor structure 23. The base of the duct or room is covered by means of simple ungrooved slabs 24 of Foamglas which may be of any convenient size and which are secured in place by mastic or asphalt. Also, similar material is employed to Iill the joints between the units.

The walls and ceiling of the duct o1' room are indicated at 26, 21 and 28 respectively. Preferably these are formed of courses of blocks, slabs or panels 29, one of which blocks is shown in detail in Fig. 15. Each panel includes plane or ship lapped side edges and a p lane or ship lapped upper edge, but the opposed lower edge is rabbeted as indicated at 30, and further is formed with a groove 3|, extending below the bottom of the rabbeted portion and providing a tongue portion. The lower horizontal course of the panels or slabs, as shown in Fig. 2, is secured in place at its lower edge by means of angle-like bars 32 preferably of wood, having a. vertical leg 33, which is nailed mounted upon spaced parallel bars 31, also loi The bar Aalso includes a horizontal web or fit in-'the" I thewall its upp'eredge. Various constructions may be gemployed to effect this result. In Y Figs. '5 and 7 is disclosed a' convenient embodiwood, shown in detail in Fig. 6 and approximately of T section including a transverse `or cross portion `38 constituting-a base nailed or otherwise secured to the members 20, 2| and-22 and a stem portion 39 having a ange 4 I secured thereto and adapted to t within the grooves 3|,

of the slabs resting thereupon so that the tongue this bar by means of nails o r screws 58 extending through openingsl 59. The plates` are disposed '10 between the edge oi' theceiling and the face of :nent means of accomplishing the function As' therein'shown, a bar 581s disposed contiguous v to the edge. of vthe'last'course 54 in the ceiling.`

Securing clips or plates 51 are mounted ,upon

` the wall and at their lower extremities, the plates portions of the blocks hook under the iianges.

Itwilll be noted that the backs of the webs are plane so that the edges of the blocks opposite. the grooved edges will tilt downwardly within the space deiined by the webs oi'the bars. The bars 32 and 31 may be formed of any convenient material, e..g., wood or metal, although,

' as above indicated,v under present conditions wood is favored, because it is, relatively nonl` strategic and it also possesses. a high degree of insulation against the transmission of heat. The portion 39Vof the bars 31 constituting the .Stemoi' the T are bored at appropriate intervals to receive short dowel-pins 42, whichpreferably t slidably in the holes in such manner that the pins can readily be forced downwardly into the upper edges of the slabs or panels, thus preventing the latter edges from tilting inwardly.. The edges of the cellular slabsare easily pierced by the pins without fracture, due to the cellularity of the glass. i

The upper corners-or edges of the uppermostslabs indicated" at 43 are conveniently secured 51'are provided with lugs 6| which initially are in a common-plane with the rest of the body 51. However, afterthe-blocks of edge course 34 have been disposed in place these lugs are bent transversely as indicated in broken line in Fig. 7 in position to 'engage'the lower faces of the blocks,

-, thus securing theoutermost edges thereof and providing a corner structure.

In the constructions shown in Figs. 8 and 10 the bars 62 Ycorresponding to the bars 56 are provided with a downwardly-extending flange or element Bti-disposed in a suitable rabbet in the A edge of the blocks ofthe outermost course. This from tilting outwardly by means of angle members 44 including wooden bars 46 and 41 secured together in convenient manner, e. g., by nails and fitting over the corner of the slabs.

The ceiling structure best shown in Figs. 1 and 4 is composed of blocks identical with those of the sides and similarly secured in position. The iirst course or row of the ceiling slabs is secured at one edge, e: g., the left edge by means of anlangle bar 48 identical with the angle bar 32 and having a ange 49 disposed in the grooves of the rst course 56, of the blocks. mainder of the courses are secured in place by means of bars 31 of the modified T section already described. The anges 52 of these bars engage in one edge of. each course. of slabs and the opposite edges of the latter are secured by means of dowels 53 identical with the dowels 42.

It will be apparent that the slabs in the side walls can be easily secured in' position-merely by hooking the groove 3| vover the appropriate iianges 36 or 4| and then tilting the upper edge of the blocksoutwardly about theanges as pivots until they engage the face portions 33 or 38 of the angle bars 32 or the T members'31.

vOf course the edge portions of the cellular slabs relatively frangible cellular material before the succeeding course is set up. K It will be apparent that special meansmust The reflange is groove'd as'indicated at 64 in Fig. 10 to receive splines 66, which are adapted tol slide into the grooves after the-blocks have been disposed in'position. These splines areV of sufficient width to project substantially beyond the grooves 64 into the mating grooves formed in the edges of the last course of blocks of the ceiling. In this construction the outerl edges of the blocks in course 54 are simply lifted up into position and the splines 66 rinserted in the grooves 64.

In the modiiication shown in Figs. 9 and 11 clip elements 61 are provided for securing course 54, These clip elements are approximately of U section and include a lower branch 68 which is adapted to-be forced into the edge of the block or. slab, an intermediate portion 69 extending upwardly over the edge of the slab to be supported and being connected to a second horizontal branch 1I extending over the upper face of the block. 'Ihisiattpr branch 1|' is also provided with an upwardly slpingsnange 12 having a downwardly bent upper edge 13 adapted to hook over a shoulder 14 of a bar 13, corresponding to the bars 56 and 62. It is to be observed that the flange 13 oi' clip 61 and the edge 16 of the shoulder 14 are so sloped as to permit a slid-f ing cam action when the outer edges o f the blocks are swung upwardly into position. v'I'he spring action of the flange 12 then causes the edge 13 to snap into position to lock or latch the blocks of the course.

In Fig. 12 is shown a metal bar which may be be `provided for securing the last course 54 in the ceiling at the corner between it and the wall of modified T construction. and may conveniently be'formed by suitably folding and bending strips or sheets of metal. Each bar includes a cross or head portion adapted to be secured to frame elements 20, 2| and 2 2 'and a stem portion 3| with a transversely bent ilange 82 that engages grooves inthe blocks. The stem portion and the ilange 82 maybe formed simply by folding the intermediate portionsof the strips of metal upon each other andthenbending laterally the flange portions 82. 'y The head portion 80 may be formedbybendin'g joutwardly an edge of each fold oi.' the metal. V Openings are formed -in the stem portion 8| at intervals to receive dowel-pins 83 corresponding.,tothel pins 42 and 53 already described.

In the construction shown in Figs. 13 and 14 vstrips or'ribbons of sheet metal are employed sentative.

to provide metallic bars as substitutes for the bars 31 and dowel-pins already describedfor supporting the edges of the panels. In the construction shown in Fig. 12, portion 85 of the metal strip corresponding in width to the head portion of the modified T is folded downwardly. A stem portion 86 is then bent along a line approximately median of the width of the portion 85. The lower edge of this stem portion -is laterally bent to provide a flange 81 for engaging the edge grooves of cellular glass, blocks or slabs. Lugs or tabs 89, secured at their upper end, are punched out at intervals along the stem or web portion 86 as best shown in Fig. 13. The lower extremities of these lugs or tabs are also bent approximately arcuately inward to provide tongue portions 9| that can be forced inwardly into the edges of the blocks as indicated in Fig. 14.

The procedure involved in the assembly of the construction of course involves first the erection of the supporting framework including vertical members and 2| and the transverse members 22. The bars 32, 31 and 44 can then be secured in place. The slabs are set by hooking the grooves in the edges of flanges 36, 4I, 41 or 52, according to the position of the block. The block is then swung into position about the ange.'

A course is thus built up. If a course has been preceded by other courses the dowels 42 or portions 9| are forced into the plain edge of the p preceding course before the foregoing setting operation. The side walls 26 and 21 are first assembled and then the ceiling 28 is erected between the side Walls. Finally the oor 24 is laid andthe joints of the structure are suitably filled with mastic or other sealer. The faces of the slabs are covered by means of a protective layer of mastic indicated at 95.

The forms of the invention herein shown and described are to be considered merely as repre- It will be apparent to those skilled in the art that numerous inodications may be made therein without departure from the spirit Yof the invention or the scope of the appended claims.

What we claim is: 1. A heat insulative wall comprising a pair of spaced parallel supporting bars, the bars each having an outwardly. projecting web and a flange on the web of one bar, said flange extending toward the second bar, the side of the web of the second bar facing the rst mentioned bar being essentially smooth and further having pin receiving openings formed therein, a course of cellulated glass slabs supported by the bars, said slabs at one edge having tongue portions hooked under said flange to prevent outward displacement of the slabs, the edges of the slabs opposite said tongues being adapted to tilt back within space between the bars in proximity to the web of the second bar and pin means in the openings in'the web of the latter bar projecting into the edges of the blocl to hold the latter edges in place.

2. A heat insulative wall comprising a pair of spaced parallel supporting bars, the bars each having an outwardly projecting web, a flange on the web of one bar extending toward the second bar, the web of the second bar on the side facing said iiange being smooth and further hav- 'ing openings formed therein, a course of cellulated glass slabs supported by the bars, said slabs being grooved upon one edge, to provide tongues, the tongues being hooked under said flange to secure the corresponding edges of the slabs in place, the opposite edges of the slabs being smooth and being adapted to tilt down into the space between the webs of the bars in contiguity to the web of the second bar and anchoring devices constituting piercing means disposed in the openings of said second bar and projecting into the corresponding edges of the slabs to hold the blocks from tilting outwardly from the space.
